ffmpeg | branch: master | Timo Rothenpieler <timo(a)rothenpieler.org> | Sat Aug 27 14:39:35 2016 +0200| [325e56479ff64c884f3bcccf922a7f7163488b89] | committer: Timo Rothenpieler avcodec/nvenc: include nvEncodeAPI v7 SDK header As Nvidia has put the most recent Video Codec SDK behind a double registration wall, of which one needs manual approval of a lenghty application, bundling this header saves everyone trying to use NVENC from that headache. The header is still MIT licensed and thus fine to bundle with ffmpeg. Not bundling this header would get ffmpeg stuck at SDK v6, which is still freely available, holding back future development of the NVENC encoder. > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=325e56479ff64c884… --- compat/nvenc/nvEncodeAPI.h | 3219 ++++++++++++++++++++++++++++++++++++++++++++ configure | 22 +- libavcodec/nvenc.h | 2 +- tests/ref/fate/source | 1 + 4 files changed, 3238 insertions(+), 6 deletions(-) diff --git a/compat/nvenc/nvEncodeAPI.h b/compat/nvenc/nvEncodeAPI.h new file mode 100644 index 0000000..18cf522 --- /dev/null +++ b/compat/nvenc/nvEncodeAPI.h @@ -0,0 +1,3219 @@ +/* + * This copyright notice applies to this header file only: + * + * Copyright (c) 2010-2015 NVIDIA Corporation + * + * Permission is hereby granted, free of charge, to any person + * obtaining a copy of this software and associated documentation + * files (the "Software"), to deal in the Software without + * restriction, including without limitation the rights to use, + * copy, modify, merge, publish, distribute, sublicense, and/or sell + * copies of the software, and to permit persons to whom the + * software is furnished to do so, subject to the following + * conditions: + * + * The above copyright notice and this permission notice shall be + * included in all copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, + * EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES + * OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND + * NONINFRINGEMENT.

These internal buffers are managed by NvEncodeAPI + and the client is not responsible for the allocating or freeing the memory of + the internal buffers. + + The client calls ::NvEncEncodePicture() API with input buffer I1 and output buffer O1. + The NvEncodeAPI decides to encode I1 as P frame and submits it to encoder + HW and returns ::NV_ENC_SUCCESS. + The client can now read the encoded data by locking the output O1 by calling + NvEncLockBitstream API. + + The client calls ::NvEncEncodePicture() API with input buffer I2 and output buffer O2. + The NvEncodeAPI decides to encode I2 as B frame and buffers I2 by copying it + to internal buffer and returns ::NV_ENC_ERR_NEED_MORE_INPUT. + The error is not fatal and it notifies client that it cannot read the encoded + data by locking the output O2 by calling ::NvEncLockBitstream() API without submitting + more work to the NvEncodeAPI interface. + + The client calls ::NvEncEncodePicture() with input buffer I3 and output buffer O3. + The NvEncodeAPI decides to encode I3 as P frame and it first submits I3 for + encoding which will be used as backward reference frame for I2. + The NvEncodeAPI then submits I2 for encoding and returns ::NV_ENC_SUCESS. Both + the submission are part of the same ::NvEncEncodePicture() function call. + The client can now read the encoded data for both the frames by locking the output + O2 followed by O3 ,by calling ::NvEncLockBitstream() API. + + The client must always lock the output in the same order in which it has submitted + to receive the encoded bitstream in correct encoding order. + + * \endcode + * + * \param [in] encoder + * Pointer to the NvEncodeAPI interface. + * \param [in,out] encodePicParams + * Pointer to the ::_NV_ENC_PIC_PARAMS structure. + * + * \return + * ::NV_ENC_SUCCESS \n + * ::NV_ENC_ERR_INVALID_PTR \n + * ::NV_ENC_ERR_INVALID_ENCODERDEVICE \n + * ::NV_ENC_ERR_DEVICE_NOT_EXIST \n + * ::NV_ENC_ERR_UNSUPPORTED_PARAM \n + * ::NV_ENC_ERR_OUT_OF_MEMORY \n + * ::NV_ENC_ERR_INVALID_PARAM \n + * ::NV_ENC_ERR_INVALID_VERSION \n + * ::NV_ENC_ERR_ENCODER_BUSY \n + * ::NV_ENC_ERR_NEED_MORE_INPUT \n + * ::NV_ENC_ERR_ENCODER_NOT_INITIALIZED \n + * ::NV_ENC_ERR_GENERIC \n + * + */ +NVENCSTATUS NVENCAPI NvEncEncodePicture (void* encoder, NV_ENC_PIC_PARAMS* encodePicParams); + + +// NvEncLockBitstream +/** + * \brief Lock output bitstream buffer + * + * This function is used to lock the bitstream buffer to read the encoded data. + * The client can only access the encoded data by calling this function. + * The pointer to client accessible encoded data is returned in the + * NV_ENC_LOCK_BITSTREAM::bitstreamBufferPtr field.

vf_colorspace: Add support for full range yuv
